Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 1, wherein the beam index information is received in a bit mask that indicates the subset of transmission beams or in a synchronization raster that indicates the subset of transmission beams.
9. The method of claim 1, wherein the set of sidelink synchronization signals further include a physical broadcast channel transmission that provides system information for the sidelink communications link.
10. The method of claim 1, wherein the first sidelink synchronization signal is a first sounding reference signal having a first reference signal sequence that provides the coarse synchronization, and the second sidelink synchronization signal is a second reference signal having a second reference signal sequence that is selected from a set of available sounding reference signal sequences to provide the identifier of the first UE and to provide the fine synchronization.
11. The method of claim 1, wherein the first sidelink synchronization signal is a primary synchronization signal and the second sidelink synchronization signal is a secondary synchronization signal.
14. The apparatus of claim 13, wherein the set of sidelink synchronization signals are associated with predefined synchronization signals of the subset of transmission beams.
15. The apparatus of claim 13, wherein the beam index information is received in a bit mask that indicates the subset of transmission beams or in a synchronization raster that indicates the subset of transmission beams.
21. The apparatus of claim 13, wherein the set of sidelink synchronization signals further include a physical broadcast channel transmission that provides system information for the sidelink communications link.
22. The apparatus of claim 13, wherein the first sidelink synchronization signal is a first sounding reference signal having a first reference signal sequence that provides the coarse synchronization, and the second sidelink synchronization signal is a second reference signal having a second reference signal sequence that is selected from a set of available sounding reference signal sequences to provide the identifier of the first UE and to provide the fine synchronization.
23. The apparatus of claim 13, wherein the first sidelink synchronization signal is a primary synchronization signal and the second sidelink synchronization signal is a secondary synchronization signal.
24. The apparatus of claim 13, wherein physical resources to be used at the first UE for transmission of the set of sidelink synchronization signals are indicated in a signal structure configured by the serving network device, and wherein the first sidelink synchronization signal and the second sidelink synchronization signal are determined based at least in part on the indicated physical resources.
26. The apparatus of claim 25, wherein the set of sidelink synchronization signals are associated with predefined synchronization signals of the subset of transmission beams.
27. The apparatus of claim 25, wherein the beam index information is received in a bit mask that indicates the subset of transmission beams or in a synchronization raster that indicates the subset of transmission beams.
29. The non-transitory computer-readable medium of claim 28, wherein the set of sidelink synchronization signals are associated with predefined synchronization signals of the subset of transmission beams.
30. The non-transitory computer-readable medium of claim 28, wherein the beam index information is received in a bit mask that indicates the subset of transmission beams or in a synchronization raster that indicates the subset of transmission beams.
